i was actually playing a quite huge video file on my dvx and then limewire crashed.....said something about being corrupted and then when my pc hang and when i restarted it i found all my downloading files empty and they were all in the incomplete files...one of the files i was earlier downloading also happened to be corrupted.....i dont know whats the reason for this.......i tried restoring my pc (system restore to an earlier time) before it crashed but still all my downloading files are gone. they're in my incomplete folder i can still play them and listen to them all right but when i resume them all each goes back to zero..........
